B             Abm
Why are there so many
E           Gb7
Songs about rainbows
B                 Abm   E    Gb7
And what's on the other side
B             Abm
Rainbow's are visions
E        Gb7
But only illusions
B                 Abm        E    Gb7
And rainbows have nothing to hide
E    
What's so amazing is that it keeps us star gazing

The lovers, the dreamers and me
B             Abm
Have you been half asleep?
E                      Gb7
And have you heard the voices
B                    Abm        E    Gb7
Well I've heard them calling my name
B           Abm              E               Gb7
Is this the sweet sound that calls the young sailors?
B                  Abm         E    Gb7
The voice might be one and the same
E    
I've heard it too many many times to ignore it
Ebm7
Ooooohh and that I think it could be


Dbm                 Gb7
Well someday we'll find it
B           Abm
The Rainbow Connection
Dbm             Gb7           B

a Rainbow Connection

The lovers, oh, the dreamers, and me
